Where How How long Takeaway Overview. They include: the testes testicles the duct system: epididymis and vas deferens sperm duct the accessory glands: seminal vesicles and prostate gland the penis. Where is sperm produced? This is a cordlike structure where the sperm mature and are stored.

The release process starts when the penis fills with blood and becomes erect. Continuing to stimulate the penis will cause an ejaculation. Mature sperm begin their journey by travelling from the epididymis to the vas deferens, which propels sperm forward with smooth muscle contractions. The sperm arrive first at the ampulla just above the prostate gland. The penis has a single tube in it called the urethra.

There are three main parts of the penis - the root, body and glans. The root is the part attached to the skin at the top of the scrotum. The body of the penis is made up of a spongy type of tissue, which swells when blood enters during an erection. The glans penis is the slightly larger area towards the end of the penis and contains the opening of the urethra. The urethra. This is the tube which passes from the bladder down the penis to the outside.

It carries both urine and semen. The main function is to give men the ability to fertilise a woman's egg ovum by producing and delivering semen. The testicles testes also make hormones which help men develop the characteristics associated with being male. This includes:.

During puberty, the level of a hormone called gonadotrophin-releasing hormone GnRH increases. GnRH is produced in a part of the brain called the hypothalamus. In turn this causes an increase in the production of two hormones from another part of the brain, called the pituitary gland. LH in the bloodstream causes cells in the testicles testes to make and release testosterone, the main male hormone.

FSH and testosterone work together to stimulate the testes to produce sperm. Each sperm cell takes between days to form and around million are produced every day. Inside the testes sperm is made in structures called the seminiferous tubules. The rigidity of the erect penis makes it easier to insert into the female's vagina during sex.

When the erect penis is stimulated, muscles around the reproductive organs contract and force the semen through the duct system and urethra. Semen is pushed out of the male's body through his urethra — this process is called ejaculation.

Each time a guy ejaculates, it can contain up to million sperm. If semen is ejaculated into a female's vagina, millions of sperm "swim" up from the vagina through the cervix and uterus to meet the egg in the fallopian tube.

It takes only one sperm to fertilize the egg. This fertilized egg is now called a zygote and contains 46 chromosomes — half from the egg and half from the sperm. Genetic material from the male and female combine so that a new individual can be created. The zygote divides again and again as it grows in the female's uterus, maturing over the course of the pregnancy into an embryo, a fetus, and finally a newborn baby.

The male genitals include: the testicles TESS-tih-kulz the duct system, which is made up of the epididymis and the vas deferens the accessory glands, which include the seminal vesicles and prostate gland the penis In a guy who has reached sexual maturity , the two oval-shaped testicles , or testes TESS-teez make and store millions of tiny sperm cells.

The male reproductive system: makes semen SEE-mun releases semen into the reproductive system of the female during sexual intercourse produces sex hormones, which help a boy develop into a sexually mature man during puberty When a baby boy is born, he has all the parts of his reproductive system in place, but it isn't until puberty that he is able to reproduce.

Although the timing of these changes is different for every guy, the stages of puberty generally follow a set sequence: During the first stage of male puberty, the scrotum and testes grow larger. Next, the penis becomes longer and the seminal vesicles and prostate gland grow. Hair begins to grow in the pubic area and later on the face and underarms.
